Shimano was founded in 1921 by Shozaburo Shimano in Sakai, Japan — a city with deep roots in precision metalworking — and has spent the century since building a component empire that accounts for roughly 70% of the global market. The first Shimano derailleur arrived in 1956. Index shifting (SIS) became the standard in 1984. Di2 electronic groupsets changed professional racing again in the years that followed. At the 2024 Tour de France, Dura-Ace R9200-equipped riders won 20 of 21 stages — the most recent chapter in a century-long record in professional cycling. Learn more at Shimano’s official website.

RA Cycles stocks the full Shimano hierarchy across road, gravel, and mountain disciplines. Dura-Ace (9200 and wireless Di2 9270) tops the road lineup — including the C36, C50, and C60 carbon disc wheelsets. Ultegra (8100/8170 Di2) brings electronic shifting to a broader price point, and GRX covers gravel across multiple tiers. On the mountain side, XTR and XT handle performance and enduro applications, with Altus serving entry-level builds. Across 695 products from $4 to $2,285, the collection covers groupset components, wheels, pedals, shoes, and small parts.
